For every traditional 100 watt bulb you replace with its LED replacement on average usage you’ll save at least £12 per year.
Given a cost of £6 for the bulb, Amazon, you’ll get your money back in 6 months and be saving the £12 each year thereafter.
I’ve been swapping incandescent bulbs for LED’s for over 12 years now and haven’t needed to replace any LED bulbs yet.
